Hello
@NETTIENOO , and welcome.
Many members have managed to reduce their HbA1c, (which is the number you are referring to) quite quickly using low carb way of eating. From much higher levels too. Above 48 is diabetic, between 42 and 48 is prediabetic. Ideally you would be aiming for below 42.
Have a read round the forums, particularly the success stories.
For more information on low carb, there are links in my signature. Read, and ask questions. Members are generally very helpful.
Best wishes. Pipp
